In the new study, Dr. Kenneth M. Hellman, a neurologist at the University of Florida School of Medicine, and his colleagues conducted a 10-year follow-up study of 264,000 participants aged 50-71. As a result, the incidence of depression was significantly higher in participants who regularly drank Diet Coke, fruit wine and sweet iced tea. People who drink 4 cans of Diet Coke a day have a 30% increased risk of depression, while drinking 4 cups of coffee a day can reduce the risk of depression by 10%.
Researchers have pointed out that the artificial sweetener aspartame in sweet drinks may be the key to the problem. Although the results of this study do not prove that sweet drinks can cause depression, there is a clear correlation between the two. Therefore, reducing the intake of sweet drinks can help reduce the risk of depression.
